Huashi 畫史, also called Mi Haiyue huashi 米海嶽畫史 or Xiangyang huaxue 襄陽畫學, is a book on painting written by the great Song-period 宋 (960-1279) calligrapher Mi Fu 米芾 (1051-1107), courtesy name Yuanzhang 元章, style Lumen Jushi 鹿門居士, Xiangyang Manshi 襄陽漫士 or Haiyue Waishi 海嶽外史, also known with the name Mi Nangong 米南宮. The short book on painting is therefore also known with the title Mi Haiyue huashi 米海岳畫史.
Mi Fu hailed from Zhenjiang 鎮江, Jiangsu, where his grandfather had built the Haiyue Studio 海嶽庵. About the early life and career of Mi Fu, histories report contradicting matters, but it was clear that he had a talent for poetry and arts. During the Xuanhe reign-period 宣和 (1119-1125) of Emperor Huizong 宋徽宗 (r. 1100-1125), Mi was appointed erudite for calligraphy and painting (shuhuaxue boshi 書畫學博士) and vice director in the Ministry of Rites (libu yuanwailang 禮部員外郎), later military prefect (zhijun 知軍) of Huainan 淮南. He was very renowned as a calligrapher who mastered the running script (xingshu 行書) and the "grass script" (caoshu 草書) as used by ancient masters like Wang Xizhi 王羲之 (303-361). Mi Fu is one of the four great masters of the Song period (Songdai si da jia 宋代四大家), the others being Cai Xiang 蔡襄 (1012-1067), Su Shi 蘇軾 (1037-1101) and Huang Tingjian 黃庭堅 (1045-1105). His teacher in painting was Dong Yuan 董源, who was a master in depicting withered trees, pines and stones. Mi Fu has also written the books Shushi 書史, a history of calligraphy, the Baozhang daifang lu 寶章待訪錄 and the Haiyue mingyan 海嶽名言. Mi Fu was known as a somewhat eccentric artist and was often called Mi Dian 米顛 "Topdown Mi".
His book Huashi is a critical history of painting from the Wei 曹魏 (220-265) to the early Song period. It includes biographies of the most important painters and a qualitative rating of their paintings. The book also explains why and how certain paintings can be rated as forgeries, and provides information about the owners and collectors of the most famous paintings. The method of mounting pictures on paper rolls is also described. His book is very important for connoisseurs of the history of painting and is a very reliable source because Mi Fu laid importance on the personal inspection of the paintings he described.
Interestingly enough, his book also includes descriptions of charts on astronomical clocks (huntian tu 渾天圖), musical notes, pitch pipes and the twelve musical modes. These do actually not belong into the category of "red-green" illustrations (danqing 丹青), i.e. painting, but Mi Fu in this respect imitates Zhang Yanyuan's 張彥遠 (early 8th cent.) book Lidai minghua ji 歷代名畫記, where illustrations on the ecliptic of the sun and the moon are to be found. Mi Fu also adds short theoretical discussions on astronomy and music that are, nonetheless, not quite reliable in the scientific sense.
